About the 450-AIYP
The Dell 450-AIYP is a Dell 1100W Titanium Hot-Plug Redundant Power Supply (Common Slot) engineered to deliver clean, redundant electrical power to Dell PowerEdge servers. Operating at high electrical efficiency with 80 PLUS certification, the 450-AIYP converts AC line input into regulated 12V server rail power while minimizing heat dissipation. In Dell's infrastructure catalog, 450-AIYP supports redundant power configurations for continuous server uptime.
Compatibility
Designed for Dell PowerEdge enterprise servers including R740, R740XD, R640, R750, the 450-AIYP slides into rear hot-plug power supply bays. The 450-AIYP operates in 1+1 redundant or 2+0 combined modes when paired with a matching power supply of identical wattage. Input voltage compatibility for the 450-AIYP covers standard data center electrical distributions.
How to identify a genuine unit
Genuine Dell 450-AIYP power supplies feature a silver label displaying DP/N 00H32R, input/output voltage and current ratings, 80 PLUS efficiency badges, and Dell regulatory approvals. In iDRAC under Power Monitoring, the 450-AIYP reports real-time wattage draw, input voltage, and thermal status.
Buying used
When evaluating a pre-owned 450-AIYP, inspect the rear blind-mate connector fingers for arcing marks, burns, or physical wear. Confirm that the internal cooling fan on the 450-AIYP spins freely without bearing rattle and that the locking release latch snaps securely into chassis bays. Verify in iDRAC that the 450-AIYP reports normal power sharing without input alerts.
